One needs to use some common sense as a developer in evaluating user CFLAGS - because there are plenty of flags that are safe, but aren't listed on that page. Several years ago, I wrote a package that was the forerunner of the 'Safe CFLAGS' page - genflags. It was close to unmaintable at the time however, so it's suffered a lot of bit-rot. With the advent of libcpuinfo, and x86info being written, it stands a much better chance of giving useful output, but that still does not supersede the common sense statement above. -- Robin Hugh Johnson E-Mail : [EMAIL PROTECTED] GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85
